I was browsing Reddit and came across a post of Richard Devine’s live rig which had something that looks like a mutable insument’s module but I couldn’t recognize. I understand that he has many customized MI modules (so many micro braids!) but there is something labeled Plarls (Plaris?) in the top right row. Is that module an oddity or a prototype or something?

It can’t be Plaits, because that name has already been taken… (prototype “hyper-Braids” that never went much further, from late 2015 or early 2016 I recall, running on an STM32F405 processor, by Patrick Dowling, name by me):
